Description:
The Climate Crisis Response System (CCRS), developed by International Climate & Environment Center (ICEC), is consisted of Early Warning System (EWS), Urban Assessment Model System (UAMS), and Urban Carbon Management System (UCMS). In this study, the impacts of climate change on the Gwangju area were assessed using a UAMS, focusing on case studies on wind flow, heat waves, fine dusts, and so on. UAMS is a system in which Weather Research and Forecasting (WRF) and Computational Fluid Dynamic (CFD) models are coupled, enabling 48-hour forecast and detailed analysis of wind flow and fine dusts. Maximum spatial resolutions simulated by WRF and CFD are 11 m and 2-20 m, respectively. Global Forecast System (GFS) re-analysis dataset was used as input data, and downscaled by seven domains in WRF modeling. The performance of WRF model was then improved by applying Digital Elevation Models (DEM) and land cover map, based on Geographic Information System (GIS). In addition, the high resolution dataset can be available, using a WRF-LES (Large Eddy Simulation) mode. The verification was done with observation data. A 3-D simulation with OpenFOAM, using WRF modeling data, was performed to predict and evaluate wind flow, temperature distribution, and air pollutant dispersion in Gwangju area. Further, UAMS can be utilized to analyze the regional impacts of climate change, and to provide crucial information for decision-making in urban planning and climate/environment policies.
